[0036] This application provides a trash can that solves the problem that existing trash cans lack mechanisms for removing odors and separating waste liquids, leading to the growth of bacteria and odors during trash accumulation and easily polluting the surrounding environment. See below for reference. Figures 1 to 6 This application describes a trash can according to some embodiments.

[0037] like Figure 1 and Figure 6 As shown, the trash can of this application includes a main body 1 and a placement box 7. The main body 1 has a trash inlet and a placement opening 3. The placement box 7 is disposed inside the main body 1 through the placement opening 3, and trash can be put into the placement box 7 through the trash inlet. The inner wall of the placement box 7 is provided with a separation net 29 and an activated carbon layer 30. The separation net 29 and the activated carbon layer 30 are arranged vertically at intervals, with the separation net 29 being closer to the trash inlet than the activated carbon layer 30.

[0038] During use, users can directly put garbage into the placement box 7 of the main body 1 through the garbage inlet. The put-in solid garbage will stay above the separation net 29, while the waste liquid will come into contact with the activated carbon layer 30 through the separation net 29, thereby achieving the effect of sorting and processing solid garbage and waste liquid. Moreover, the waste liquid and odor molecules inside the main body 1 will be absorbed by the activated carbon, thereby ensuring that the garbage can and the surrounding environment will not be polluted.

[0039] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the trash can also includes an electric push rod 20 and a pressure plate 21 fixed to the output shaft of the electric push rod 20. The electric push rod 20 is fixed to the top of the inner wall of the main body 1, and the placement box 7 is set at the bottom of the main body 1. The inner wall of the placement box 7 and the separation net 29 form an open trash placement groove. The pressure plate 21 is set directly opposite the trash placement groove, and the size of the pressure plate 21 matches that of the trash placement groove.

[0040] This design allows the electric pusher 20 to operate, causing the pressure plate 21 to compress the waste during the waste disposal process. Solid waste remains above the separation mesh 29 (wire mesh), while waste liquid passes through the mesh and contacts the activated carbon layer 30. This achieves the separation of solid waste and waste liquid, effectively absorbing odor molecules and preventing odor and waste liquid fermentation from polluting the environment, thus improving the practicality of the trash can. Furthermore, the pressure plate 21 reduces the space occupied by the waste after disposal, ensuring it is compressed and increasing the amount of waste the trash can can hold.

[0041] like Figure 1 and Figure 5As shown, the trash can also includes a sealing structure 23. The main body 1 has an installation opening 2, and the sealing structure 23 is installed inside the main body 1 through the installation opening 2. The sealing structure 23 includes a horizontally arranged sealing plate 232, a vertically arranged support plate, and an inclined first plate 231. The sealing plate 232 is connected to the top of the support plate and fits against the wall of the installation opening 2. The two sides of the support plate are slidably connected to the main body 1. The first end of the first inclined plate 231 is connected to the top of the support plate and is located on the side of the support plate opposite to the installation opening 2. The tail end of the first inclined plate 231 is lower than the head end and points towards the trash placement trough. The sealing structure 23 can move laterally. When the sealing structure 23 extends out of the main body 1, the first inclined plate 231 and the wall of the installation opening 2 form a trash inlet. When the sealing structure 23 retracts into the main body 1, the sealing plate 232 seals against the wall of the installation opening 2.

[0042] With this configuration, the waste inlet is located at the sealing structure 23. When the sealing structure 23 extends outward, the first inclined plate 231 on the inner side of the sealing structure 23 guides the waste into the placement box 7. Figure 5 As shown, because the sealing structure 23 includes the first inclined plate 231, after the sealing structure 23 is removed, the user can directly throw the garbage onto the sealing structure 23, thereby causing the garbage to be automatically guided into the placement box 7.

[0043] As an example, such as Figure 1 and Figure 5 As shown, the trash can of this application also includes a rack 25, a gear 22, and a motor 8. The motor 8 is fixed to the outer wall of the body 1, the output shaft of the motor 8 is fixedly connected to the gear 22, the gear 22 meshes with the rack 25, the rack 25 is fixedly connected to the first inclined plate 231, and the rack 25 is slidably connected to the body 1. The rack 25 is arranged laterally, and the motor 8 can drive the sealing structure 23 to move laterally via the rack 25.

[0044] With this configuration, the motor 8, rack 25, and gear 22 allow the motor 8 to automatically move out of the sealing structure 23 during operation by meshing the gear 22 with the rack 25. This makes it convenient for users to directly put garbage into the main body 1 without having to manually open the garbage can to dispose of the garbage, thus improving the automation of the garbage can. At the same time, after the sealing structure 23 is reset, the tight fit between the sealing structure 23 and the inner wall of the mounting port 2 can seal the main body 1, preventing garbage leakage and thus improving the sealing performance of the garbage can.

[0045] Preferably, in the embodiments of this application, such as Figure 1 and Figure 5As shown, the sealing structure 23 includes a vertically arranged support plate. Limiting strips 24 are fixed on both sides of the support plate. The two sides of the support plate are slidably connected to the body 1. Limiting grooves 9 are opened on both sides of the inner wall of the body 1. The inner wall of the limiting grooves 9 is slidably connected to the limiting strips 24. The top of the sealing plate 232 of the sealing structure 23 can fit tightly against the inner wall of the mounting port 2.

[0046] Furthermore, in the embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the trash can also includes a load-bearing plate 10, a movable plate 12, a base plate 15, a return spring 19, a lifting rod 18, a miniature pressure transmitter 17, and a controller. The controller is communicatively connected to the micro pressure transmitter 17, the electric push rod 20, and the motor 8. A load-bearing plate 10 is fixed to the outer wall of the bottom of the main body 1. A movable groove 14 (square groove) is opened on the top of the load-bearing plate 10. A base plate 15 is fixed to the inner wall of the bottom of the movable groove 14. A circular hole 16 is opened on the top of the base plate 15, and a controller is also fixed thereon. The micro pressure transmitter 17 is fixed to the bottom of the circular hole 16. A lifting rod 18 is slidably sleeved on the inner wall of the circular hole 16. A limit plate is fixed to the top of the lifting rod 18. A return spring 19 abuts between the base plate 15 and the limit plate. A movable plate 12 is slidably connected to the top of the load-bearing plate 10 and covers the movable groove 14. The top of the lifting rod 18 is fixedly connected to the movable plate 12. The movable plate 12 can be lowered by external force to squeeze the micro pressure transmitter 17 through the lifting rod 18. The controller controls the motor 8 to rotate forward or backward according to the signal sent by the micro pressure transmitter 17.

[0047] This design allows users to stand directly on the movable plate 12 after installation and use their own weight to press the movable plate 12 down, thereby causing the lifting rod 18 to press the micro pressure transmitter 17. This achieves the effect of removing the sealing structure 23 without the user having to manually operate the motor 8, thus improving the intelligence and practicality of the trash can.

[0048] In other words, through the set controller structure, when the micro pressure transmitter 17 is in contact with the lifting rod 18, the controller will automatically control the motor 8 to operate, thereby achieving the effect that the motor 8 will automatically operate and make the gear 22 rotate to drive the sealing structure 23 to move, thus ensuring the normal operation of the trash can.

[0049] In other words, when a user stands on the movable plate 12, the movable plate 12 will deform due to the weight of the human body. That is, the middle part will deform, causing the lifting rod 18 to squeeze the miniature pressure transmitter 17 to generate pressure, thereby achieving the effect of pressure detection. This ensures that the device can automatically detect that someone is standing on the movable plate 12, thus causing the device to automatically turn on.

[0050] In this embodiment, the micro pressure transmitter 17 can be a CMP 8271 CANopen micro pressure transmitter, which accurately collects pressure data and converts it into an electrical signal so that the controller can operate the motor 8. When the pressure disappears, that is, after the user has finished disposing of the garbage and walked out of the range of the movable plate 12, the pressure disappears and the controller controls the motor 8 to rotate in the opposite direction to achieve the effect of recycling the sealing structure 23.

[0051] Furthermore, in the embodiments of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the trash can also includes a baffle 4, a first retaining spring 32, a second retaining spring 27, a button 6, a connecting rod 31, and a locking pin 28. The baffle 4 is installed inside the main body 1 through the mounting port 2. The baffle 4 is located below the sealing structure 23. The placement port 3 and the mounting port 2 are respectively opened on two adjacent side walls of the main body 1.

[0052] like Figure 6 As shown, the baffle 4 has a first circular groove 5 inside, and a first retaining spring 32 is provided inside the first circular groove 5. The first retaining spring 32 is sleeved on the connecting rod 31. One end of the first retaining spring 32 abuts against the inner wall of the first circular groove 5. The button 6 passes through the baffle 4 and abuts against the other end of the first retaining spring 32. The button 6 and the connecting rod 31 are integrally formed. The side wall of the placement box 7 has a second circular groove 26 inside, and a second retaining spring 27 is provided inside the second circular groove 26. The second retaining spring 27 abuts against the inner wall of the second circular groove 26 and between the retaining pin 28. One end of the retaining pin 28 abuts against the second retaining spring 27, and the other end passes through the baffle 4 and contacts the connecting rod 31.

[0053] After pressing button 6, the button 6 presses against the latch 28 until the placement box 7 is in a movable state, allowing the placement box 7 to be removed. In any state, pressing button 6 will detach the placement box 7. When securing the placement box 7, after insertion, the latch 28 pops out and inserts into the round hole 16 of the baffle 4, preventing the placement box 7 from becoming loose and ensuring its stability.

[0054] With this design, the solid-liquid separation effect of the wire mesh decreases during the operation of the activated carbon layer 30 and the wire mesh, while the absorption effect of the activated carbon layer 30 on odor molecules also decreases. Users can directly remove the placement box 7 by pressing button 6, facilitating its disassembly and assembly, thus improving the user's maintenance efficiency for the trash can. Specifically, pressing button 6 disengages the latch 28 from the baffle 4, placing the placement box 7 in a movable connection with the baffle 4. This allows the user to easily remove the placement box 7 to clean or replace the wire mesh and activated carbon layer 30, further improving the user's maintenance efficiency for the trash can.

[0055] Furthermore, in the embodiments of this application, such as Figure 5 As shown, a second inclined plate 41 is provided on the top of the baffle 4. The second inclined plate 41 is located at the bottom of the first inclined plate 231, and the first inclined plate 231 is parallel to the second inclined plate 41. When the sealing structure 23 extends out of the body 1, the bottom of the first inclined plate 231 is in contact with the top of the second inclined plate 41.

[0056] With this configuration, after the garbage is deposited, to prevent the first inclined plate 231 from deforming due to excessive impact from the height difference and weight of the garbage, the second inclined plate 41 can support the first inclined plate 231, thereby distributing the pressure. Therefore, the first inclined plate 231 will not deform after receiving the garbage, preventing it from falling into the placement box 7. In other words, when the first inclined plate 231 is removed, its bottom fits against the top of the second inclined plate 41, supporting it. At this point, the device is activated, and the user can deposit the garbage, which is guided directly by the first inclined plate 231.

[0057] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the trash can also includes a drain pipe 11, and a drain hole is provided at the bottom of the placement box 7. The drain pipe 11 is connected to the interior of the placement box 7 through the drain hole.

[0058] This design, through the structure of the drain hole, allows the pressure plate 21 to compress the garbage, while the wire mesh isolates the solid waste, thus separating the waste liquid from the solid waste and achieving the effect of discharging the waste liquid. The drain hole guides the waste liquid into the drain pipe 11 for centralized discharge, facilitating centralized treatment of the waste liquid at the end of the drain pipe 11. Preferably, the drain pipe 11 is embedded in the ground 13, and the garbage can of this application is placed on the ground 13. The drain pipe 11 will discharge the sewage below the ground 13, reducing the space occupied by the pipe. The drain pipe 11 can centrally discharge sewage, preventing leakage and facilitating disposal.

[0059] Working principle: First, after the user installs the trash can on the ground 13, the user can stand directly on the movable plate 12 and use their own weight to lower the movable plate 12. This causes the lifting rod 18 to press against the micro pressure transmitter 17, which, in conjunction with the controller, automatically controls the motor 8 to operate. This causes the gear 22 to rotate and move out of the sealing structure 23, thus opening the trash can without manual operation by the user, improving the intelligence of the trash can. After the user leaves the area of ​​the movable plate 12 after disposing of trash, the pressure disappears, causing the output shaft of the motor 8 to reverse and reset the sealing structure 23. This seals the body 1, preventing leakage of trash and waste liquid, thereby improving the airtightness of the trash can. During the process of trash accumulation, the liquid inside the trash, the ambient temperature, and bacteria will cause leakage. In cases where waste liquid is generated, the pressure plate 21 is lowered by extending the output shaft of the electric push rod 20 to compress the garbage. This prevents solid garbage from passing through the wire mesh, while the waste liquid passes through the wire mesh and comes into contact with the activated carbon layer 30. The activated carbon layer 30 absorbs the waste liquid and odor molecules inside the main body 1. Finally, the waste liquid is discharged through the drain pipe 11. Users can directly treat the waste liquid discharged from the end of the drain pipe 11, thus achieving the effect of sorting and treating garbage and waste liquid. After the wire mesh and activated carbon layer 30 have been used for a long time, the user can press the button 6 to release the latch 28 from the baffle, making it easy for the user to remove the placement box to clean or replace the wire mesh and activated carbon layer 30, improving the user's maintenance efficiency of the garbage can.

[0060] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
